WESPC Diesel Engine ULPK0031 Fuel Lift Pump For Perkins Engine Parts

Application:

ULPK0031 is the diaphragm-type fuel lift pump that primes and feeds Perkins T4.236 and AT4.236 turbocharged diesel engines (4.0 L, 4-cylinder) which are widely used across agricultural tractors such as Massey Ferguson 2400- and 3400-series, combine harvesters like the MF 7200 range, generator sets from FG Wilson and Pramac, and industrial machinery built by JCB and Manitou. The pump mounts directly to the left-hand timing-gear cover and supplies filtered fuel to the high-pressure injection system across engine speeds from 800 r/min idle to 2 400 r/min rated.

Technical specifications:

The cast-aluminium single-diaphragm unit delivers 90 L/h at 300 kPa and 2 000 r/min; inlet and outlet ports are 8 mm hose-barb fittings. SAE J744 size 1 flange with two M8 threaded holes on 60 mm centres is actuated by the camshaft eccentric. Diaphragm diameter is 72 mm, stroke 5 mm, and the integral bypass valve limits pressure to 350 kPa. All sealing gaskets are FKM (Viton) for biodiesel compatibility up to B20 and arctic-grade diesel down to −40 °C.

Material & performance features:

The powder-coated aluminium housing resists corrosion and stone-chip damage; the multi-layer fabric-reinforced nitrile diaphragm is PTFE-faced for low swell and extended flex life. Induction-hardened medium-carbon steel lever and push-rod resist wear, while the stainless-steel return spring prevents sag in humid climates. A translucent sight-bowl sediment filter with 80 µm paper element traps water and debris, and the spring-loaded priming lever allows rapid manual bleeding after service. Lightweight, maintenance-free sealed bearings and quiet operation suit continuous-duty agricultural, construction and generator applications.
